Abstract: A novel method is proposed for determining the dew point of a gas by means of a light ray reflected at a dew-point mirror (3). For measurements of fairly low dew points, in particular at temperatures of -50 DEG C to -95 DEG C, the dew-point mirror (3) is first exposed for a short time to a gas having a high water content. This achieves the result that an initial, fairly thick dew layer which appreciably shortens the measurement time is built up on the dew-point mirror (3). To carry out this method, a dew-point measuring system is proposed which has a gas valve (24), an injector pump (25) and a moistening unit (26) in a secondary circuit (23). A hygroscopic polyamide hose which ensures maintenance-free moistening of the gas by water molecules diffused into it has proved particularly advantageous. <IMAGE>

Abstract: Laterally stabilized, water-miscible polyester polyurethane resins, useful as principal binder resins and as pigment grind resins in water-borne coating systems are the reaction product of one or more polyols, one or more polyisocyanates, and a polyester prepolymer formed by the reaction of a polyether alcohol, one or more polyols, and one or more polyfunctional carboxylic acids. The resins have a polyester polyurethane backbone with pendant polyether groups, attached to the polyester segments of the backbone, which serves to solubilize and stabilize the resins in aqueous media. The resins have small dispersion particle size at the same or higher molecular weights than similar prior art resins, and produce better metal flake orientation when used as the principal resins in base coat formulations which contain aluminum and mica particles for "metallic" effect coating finishes.

Abstract: In the case of continuous casting moulds with two broad-side walls, which are arranged opposite one another on supporting frames in such a way that their shape gives a funnel-shaped free space and between which narrow-side walls adjustable relative to one another for the purpose of adjusting the format width are firmly clamped, mechanical clamping elements in operative connection with hydraulic cylinders being provided for clamping the narrow-side walls, the disassembly of the entire mould after a break-out or overflow and the cleaning of the narrow- and broad-side walls is relatively difficult due to the small opening width of the broad-side walls. This is particularly true for the maintenance of the mould and for the installation and removal of the narrow- and broad-side walls with their supporting elements. These difficulties are eliminated in a simple manner according to the invention by virtue of the fact that the supporting frames (1, 2) with their broad-side walls (9) are arranged in such a way in the continuous casting mould and connected in such a way to the clamping elements (7, 8) that they can be adjusted both towards one another and away from one another. In this way, it is possible for the supporting frames with their broad-side walls to be spread apart to such an extent that they are accessible from both sides, especially in the region of the narrow-side walls and can be cleaned, maintained and exchanged very easily. In particular, following a break-out or overflow the complete mould can be lifted away upwards over the funnel-shaped strand end solidified in the mould.

Abstract: A method and apparatus for improving the output torque response of a crankcase scavenged, two-stroke engine 10 to a change in throttle position TP by adjusting the conventional timing of cylinder fuel injection FIT as a function of the position of the throttle 22 and the time rate of change in the throttle position TPF. Preferably, throttle position TP is measured with a potentiometer 44 connected to the engine air intake throttle 22, and then filtered with a filter 56 having a first order lag characteristic. Injection timing FIT is advanced based upon a first predetermined schedule as a function of the measured throttle position TP. The difference DIFF between the measured and filtered throttle positions represents an indication of the time rate of change of throttle position and is employed to advance or retard timing in accordance with the second predetermined schedule, depending upon whether the difference is positive or negative, respectively. As a result, a substantially linear relationship is established between the output torque of the engine 10 and the position of the throttle 22 over its entire range of movement, and the amount of time required for the engine 10 to respond to abrupt changes in throttle is reduced.

Abstract: An ohmically or electrothermally controlled valve gate for injection molding apparatus comprises three concentrically located tubes (16,20,22) in intimate contact with each other. The innermost tube (16) is an electrode and also serves as the passage for flowing molding material. The outermost (20) of the three tubes is also an electrode. The intermediate tube (22) is a resistive heating element comprising a mixture of at least two highly compacted powders. One powder is an electrical conductor, while the other powder, which serves as a binder for the first powder, is an electrical insulator but a good thermal conductor. Current flow between the electrodes (16,20) occurs at points of contact between adjacent particles of the conductive powder. Thus, the electrical resistance and therefore the generation of heat is controlled by the composition and quantity of binder in the heating element. The generated heat is conducted through the inner electrode tube to the flowing plastic to melt the plastic and "open" the gate. Interruption or reduction of current flow reduces the heat and permits the plastic in the passage (18) to freeze, thereby "closing" the gate.
